DRAINMOD can also use files containing daily PET data. An example from a PET file is shown in Table 1. There are two lines for each month. The first line contains the station ID in columns 1-6, the year in columns 8-11 and the month in columns 12-13. The daily PET in hundredths of inches for day 1 of the month is in columns 17-20.. PET for day 2 is in columns 21-24 and so on. Line 1 contains the daily PET for days 1-14 and line 2 for days 15-31 (Table 2).
